化学生物絮凝与化学絮凝工艺比较研究

A Comparative Study between Chemical-Biological Flocculation and Chemical Flocculation Processes

对化学生物絮凝与化学絮凝两种工艺进行比较,两套工艺处理同一城市污水的试验结果表明:化学生物絮凝工艺出水CODCr的去除率比化学絮凝工艺要高约10%,TP平均去除率高约6%,SS平均去除率高约6%,而两工艺对NH3-N的去除能力均较小。从试验结果分析,化学生物絮凝工艺对城市污水的处理效果要优于化学絮凝工艺。

The two processes of chemical-biological flocculation process and chemical flocculation process are compared. The result of a test using these two processes in the treatment of the wastewater from the same city shows that the average removal rates of CODCr, TP and SS of the effluent water with chemical-biological process are 10%, 6% and 6% higher respectively than with chemical flocculation process, while the NH3-N-removing abilities of both of the two processes are relatively small. It can be seen from the analysis of the results of the test that the result of the treatment of municipal wastewater by chemical-biological flocculation process is better than by chemical flocculation process.
